The trapezoidal rule for numerical quadrature. This formula with two quadrature points is exact for linear polynomials.
The class is poorly named since the proper name of the quadrature formula is "trapezoidal rule", or sometimes also called the "trapezoid rule". The misnomer results from the fact that its original authors' poor English language skills led them to translate the name incorrectly from the German "Trapezregel".
